/// tip

在 raise 一個 `HTTPException` 時，你可以將任何可轉為 JSON 的值作為 `detail` 參數，不只限於 `str`。

你可以傳入 `dict`、`list` 等。

**FastAPI** 會自動處理並轉為 JSON。

## 新增自訂標頭 { #add-custom-headers }

有些情況需要在 HTTP 錯誤回應中加入自訂標頭，例如某些安全性情境。

你大概不需要在程式碼中直接使用。

但若你在進階情境中需要，可以這樣加入自訂標頭：

{* ../../docs_src/handling_errors/tutorial002_py310.py hl[14] *}

## 安裝自訂例外處理器 { #install-custom-exception-handlers }

				err = msgp.WrapError(err)
				return
			}
		}

	return
}

// EncodeMsg implements msgp.Encodable
func (z *BucketMetadata) EncodeMsg(en *msgp.Writer) (err error) {
	// map header, size 25
	// write "Name"
	err = en.Append(0xde, 0x0, 0x19, 0xa4, 0x4e, 0x61, 0x6d, 0x65)
	if err != nil {
		return
	}
	err = en.WriteString(z.Name)
	if err != nil {
		err = msgp.WrapError(err, "Name")

It keeps the function signatures working in other contexts, respects the types, allows reusability.

### In Parameter Declarations

Use `Annotated` for parameter declarations, including `Path`, `Query`, `Header`, etc.:

```python
from typing import Annotated

from fastapi import FastAPI, Path, Query

app = FastAPI()


@app.get("/items/{item_id}")
async def read_item(

		for s.skipCount > 0 {
			if l > s.skipCount {
				l = s.skipCount
			}
			n, err := s.Reader.Read(tmp[:l])
			if err != nil {
				return 0, err
			}
			s.skipCount -= int64(n)
		}
	}
	return s.Reader.Read(p)
}

// NewSkipReader - creates a SkipReader
func NewSkipReader(r io.Reader, n int64) io.Reader {
	return &SkipReader{r, n}
}

mvn clean install -pl fess-crawler
